The data layer that tax software forgot to build.

Avalara, Vertex, and TaxJar lock regulation data inside compliance platforms. Accountants still track changes manually. Developers can't get clean feeds. The foundation is missing, and everyone's building on sand.

What TaxRadar does

Regulation data as infrastructure, not as a feature buried in software.

🔍

Jurisdiction Search

Look up current tax rules for any U.S. state, county, or city. Structured, queryable, always current.

⚡

Combined Rates

See the full tax picture: state base rate, county additions, and city-level taxes rolled into one combined rate.

📊

Structured Data

Every jurisdiction tagged by type, with effective dates and source references. Clean enough to build on.

🔧

REST API

JSON endpoints for search, state lookup, and jurisdiction details. Integrate tax data into any product or workflow.

Built for developers.

Clean REST API with structured JSON responses. Query jurisdictions by state, county, city, or free-text search. No API key required during beta.

// Search for tax rates
const res = await fetch(
  "/api/jurisdictions/search?q=seattle"
);
const data = await res.json();
// Returns structured results:
{
  "city": "Seattle",
  "state_code": "WA",
  "combined_rate": 10.35,
  "effective_date": "2026-01-01"
}

Tax data shouldn't require an enterprise contract to access.

TaxRadar is building the open data layer for tax regulation. Structured. Searchable. Affordable. The way it should have been from the start.
